A disposable absorbent garment includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet. The topsheet, backsheet and absorbent core are assembled together to form a layered assembly including a front region, a back region, and a crotch region disposed between the front region and the back region. The layered assembly has a longitudinal plane that extends substantially centrally through the front, back and crotch regions. Each of the front and back regions further includes a pair of ear portions extending in substantially opposite lateral directions with respect to the longitudinal plane. Further, each of the ear portions includes a layered section of a material layer and a stretchable member extendible between a contracted configuration and an extended configuration. The material layer is secured to the stretchable member when the stretchable member is disposed in an extended configuration and the outside surface of the material layer is disposed in a substantially planar configuration. In this way, the material layer is, thereafter, extendible with the stretchable member from a contracted configuration to an extended configuration wherein its outer surface is returned to its substantially planar configuration.

Disposable absorbent garment having stretchable side waist regions

A disposable absorbent article is disclosed that is partially defined by a pair of longitudinally extending side edges and a pair of end edges extending between the side edges, and includes a topsheet layer, a backsheet layer, and an absorbent core disposed between the topsheet and the backsheet. The disposable absorbent article also has a pair of side wall structures each having a pair of oppositely positioned end portions. A first side wall structure extends generally longitudinally between the core and one of the side edges and the other side wall structure extends generally longitudinal between the core and the other side edge. Further, an end strip constructed from an elastic material is positioned substantially adjacent each one of the end edges, and extends laterally between the side edges. Each of the end strips includes a fixed elastic end section disposed adjacent the end edge and secured to the topsheet, a fixed intermediate section positioned longitudinally inward of the fixed end section, and a movable, elastic inward section positioned longitudinally inward of the intermediate section.

Disposable absorbent article with containment structure

A disposable absorbent article partially defined by a pair of longitudinally extending side edges and a pair of end edges extending between the side edges, includes a topsheet layer, a backsheet layer, and an absorbent core disposed between the topsheet and the backsheet. The disposable absorbent article also has a pair of side wall structures each having a pair of oppositely positioned end portions. A first side wall structure extends generally longitudinally between the core and one of the side edges and the other side wall structure extends generally longitudinally between the core and the other side edge. Further, an end strip constructed from an elastic material is positioned substantially adjacent each one of the end edges, and extends laterally between the side edges. Each of the end strips includes a fixed elastic end section disposed adjacent the end edge and secured to the topsheet, a fixed intermediate section positioned longitudinally inward of the fixed end section, and a movable, elastic inward section positioned longitudinally inward of the intermediate section. The fixed elastic section forms a waistband portion each of the front and back waist regions of the article. The intermediate section has a plurality of voids or apertures which are employed to substantially de-elasticize the intermediate section. The inward section includes a central portion spaced from the topsheet and the absorbent core, and a pair of side portions. These side portions are secured to the end portions of the side wall structures, thereby applying a contractile force between the side wall structures such the side wall structures (as well as the side edges of the article) are biased upwardly. The side wall structures and the inward sections are, therefore, secured to one another and disposed to define the sidewalls of a relatively deep containment pocket located in the crotch region.

A disposable absorbent garment includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet. The topsheet, the backsheet, and the absorbent core form a layered assembly including a front region, a back region, and a crotch region disposed between the front region and the back region. The garment is characterized by a vertical longitudinal plane that extends substantially centrally through the front, back and crotch regions. Each of the front and back regions includes a pair of ear portions extending in substantially opposite lateral directions with respect to the longitudinal plane. Each ear portion is a breathable stretchable layer assembly having a plurality of vent sites. Further, each ear portion includes an outer layer that is an extension of the backsheet and which extends laterally to the side edge of the ear portion, and an inner layer that is an extension of the topsheet and which also extends laterally to the side edge of the ear portion. The ear portion also includes a stretchable material layer secured between the inner layer and the outer layer. The topsheet includes a central section that is generally disposed in a center section of the garment and over the core. Each of a pair of side sections of the topsheet extends laterally and forms the inner layer of two of the ear portions. The side section also forms an outer wall section of a leg cuff that extends longitudinally along the lateral side of the core. An inner wall section of the leg cuff is a portion of a substantially impervious material that extends below the leg cuff to sealingly engage the side edge of a polymeric film barrier disposed underneath the core. The substantially impervious material and the polymeric film barrier combine to form a substantially impervious containment structure about the sides and bottom of the core.

Disposable absorbent garment such as a diaper or training pants and a process of making the same

A disposable absorbent article includes a topsheet, a backsheet and an absorbent core disposed therebetween. One or more of the backsheet, topsheet, and absorbent core is constructed of an absorbent composite that includes an absorbent layer of hydratable fine fibers in the form of microfibril obtained from cellulose or a derivative thereof and super absorbent polymer (SAP) particles bonded together by the hydratable fibers, and a nonwoven substrate supporting the absorbent layer such as SMS. The absorbent layer is coated over the surface of the nonwoven substrate. The core may include one uniform layer of the absorbent composite or a composite having one layer of the nonwoven substrate and a plurality of segmented absorbent layers applied thereon. In the latter design, the absorbent layers are spaced apart from one another to expose surface sections of the substrate. These non-coated surface sections provide wicking zones which allow room for the absorbent layers to expand and prevent gel blocking.

Disposable absorbent article employing an absorbent composite and method of making the same

A disposable absorbent article defined by a pair of longitudinally extending side edges and a pair of end edges extending between the side edges, has a front waist region, a back waist region, and a crotch region located between the waist regions. The disposable absorbent article also includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet. The topsheet is provided with a plurality of openings which direct bodily exudates received into or by the crotch region to a storage space disposed below the topsheet. The topsheet is spaced generally upward from the core such that the storage space is disposed between the topsheet and the core. The disposable absorbent article further includes at least one or more elongated elastic strands which are attached to the topsheet so as to space or urge the topsheet generally upwardly from the core. Moreover, portions of the topsheet between the elastic strands are tacked down to create depressions between the strands and each of the openings are located generally in one of these depressions.

Disposable article with containment structure

A disposable garment and method of manufacturing such whereby profile cuts are made near the longitudinal edges of an absorbent pad assembly to create leg cut-out pieces or noodles. The noodles remain attached to the absorbent pad assembly at a point proximal to a center point of the absorbent pad assembly. The noodles are then folded toward the interior surface of the absorbent pad assembly about the point of attachment and are attached to the interior surface by an adhesive. An outer folding strip of each noodle is then folded back upon the respective noodles and secured to the noodle and the absorbent pad assembly by an adhesive, thereby creating an effective leakage control shield without the need to discard unused material in the manufacturing process.
